Definably primitive group actions
Abstract: One of the amazing things about Galois theory is that sometimes you can convert a natural motivational question to a question about group actions. This is incredibly useful, since group theory has some of the deepest classification results in mathematics.
In model theory, we have a definable version of Galois theory, and numerous questions can be reduced to the basic building blocks in our category, definably primitive group actions. We'll talk about this general picture and some natural open questions.
